A gas generator includes an ignition charge, at least one ignition element for igniting the ignition charge, a storage chamber containing a compressed gas, which storage chamber is closed by a closure element, and an impact element destroying the closure element under pressure. A piston is provided as the impact element, which piston, after the destruction of the closure element, forms an exit gap with the opening closed by the closure element. The cross-sectional area of which exit gap changes in according to the position of the piston.

Gas generator

A temperature fuse for gas-generating mixtures consists of substances or mixtures of substances that have lower detonation points or decomposition points than the gas-generating mixture. In particular, the temperature fuse contains substances or mixtures of substances that thermally decompose exothermically in a narrowly restricted temperature range. The evolution of heat that results ignites the gas-generating mixture.

Temperature fuse with lower detonation point

The hybrid gas generator to inflate airbags comprises two combustion chambers (,), in each of which a solid material charge (,) is placed, and a storage chamber (,) containing a pressurized storage gas. The storage chamber (,) is connected to diffusion chamber (,) by a closing member (,) which can be perforated. The first solid material charge (,), and the second solid material charge (,) can, for instance, can be sequentially ignited by separate igniter elements (,), thereby determining the pressure accumulation.
